Last week, UrbanHail, a Boston startup which developed an app to provide real-time price comparisons for Uber, Lyft and taxi services, found its access to the Uber API revoked for violating Uber's terms of service. The startup claims that Uber's actions are "anti-competitive."
An application that shows you if your train will be late, and that in real-time! Even better, imagine that bundled with an API that gives you access to all that data. So happened in Germany with the application Zugmonitor (German for train monitor) and the corresponding Zugmonitor API.
